2301.20.00.90 - Other

This HTS category, 2301.20.00.90, encompasses flours, meals, and pellets derived from fish, crustaceans, mollusks, or other aquatic invertebrates that are not suitable for direct human consumption. This includes by-products and waste materials from the processing of seafood, which are typically processed into these forms for use in animal feed or other industrial applications. The key characteristic is the origin from aquatic life and the processed, non-consumable form.

This "Other" designation differentiates it from the specifically listed herring meal and pilchard meal found under code 2301.20.00.10. While both fall under the broader category of fish-based meals, 2301.20.00.90 serves as a residual classification for all other types of aquatic invertebrate meals, flours, and pellets not explicitly enumerated in the preceding sibling category. This ensures that all non-human-consumable aquatic meals are accounted for within the tariff schedule.

As this is a leaf node, there are no further subcategories. Classification under this heading is determined by the absence of specific enumeration in preceding subheadings and the fulfillment of the general criteria for flours, meals, and pellets of fish and other aquatic invertebrates unfit for human consumption. Practical classification relies on verifying the source material and the processing method to confirm its suitability as animal feed ingredients or similar industrial outputs.
